If you ever worked shifts and transitioned to a 9 to 5 job, how difficult was the change?

I’m a nurse working shifts and sometimes 5 days without a pause and I still don’t know if I’m gonna take one of the 2 9 to 5 jobs my hospital system has offered. I’d earn less money, but I’m already 45 years old and I don’t know if I should call it quits and settle for a regular job 5 days a week and free weekends...
